St Andrew’s Church, an 18th‑century landmark in the UK, recently underwent a sensitive heating upgrade that preserves its historic character while delivering modern comfort. Faced with uneven warmth, slow heat‑up times and visual intrusion from the original radiator network, the project team specified an innovative heat pump system to replace traditional radiators. After an international tender, Airosd was chosen for its leading heat pump technology and experience in historic buildings. The proposed solution centers on a modular air source heat pump system, combining three high‑efficiency units with custom controls and renewable integration. Project Highlights Heritage‑Sensitive Installation – The new heat pump system fit discreetly into existing service voids, avoiding any disturbance to St Andrew’s stone walls or stained‑glass windows. – Concealed pipework connects to underfloor heating and fan‑coil terminals, replacing bulky radiators without altering the nave’s appearance. Advanced Heat Pump Technology – Each air source heat pump draws ambient air and upgrades it to usable heat via inverter‑driven compressors. – EVI jet‑injection and smart defrost algorithms ensure reliable operation even in sub‑zero conditions, extending the scope of geothermal heating alternatives. Smart Controls & Efficiency – A central controller monitors indoor and outdoor sensors, automatically modulating output for maximum efficiency. This heat pump system can adapt to varying attendance patterns—from quiet weekday services to full‑house Sunday worship. – Integrated BMS compatibility means the air source heat pump system links seamlessly with lighting and ventilation, further reducing energy demand. Renewable Energy Integration – To complement the air source heat pump, rooftop PV panels feed a battery bank. Surplus electricity powers pumps and circulation, minimizing grid reliance and cutting carbon emissions. – When sunlight is insufficient, the heat pump system draws only the necessary grid energy, optimizing life‑cycle costs. Performance & Comfort Since commissioning, St Andrew’s has seen a 40% reduction in heating energy consumption compared to the old radiator network. Thanks to underfloor circuits and fan coils, warmth is uniform and responsive—an outcome traditional geothermal heating retrofit approaches could not achieve without extensive excavation. Why Heat Pump Technology? – Sustainability: Zero on‑site combustion and up to 5.0 COP (Coefficient of Performance) yield dramatic CO₂ savings. – Versatility: Whether on frosty winter mornings or mild autumn days, the air source heat pump adapts output, maintaining a stable interior climate. – Heritage‑Friendly: Minimal visual impact and non‑invasive installation protect historic fabric. By choosing Airosd’s air source heat pump system, St Andrew’s Church now combines centuries‑old grandeur with 21st‑century efficiency, setting a benchmark for historic building retrofits across Europe.

AIROSD’s air source heat pump provides reliable heating in Xinjiang’s harsh climate of cold, sandstorms, and temperature swings. Using four technologies—EVI ultra-low-temp heating to −40 °C, AI-driven defrosting, V-type evaporator for sand resistance, and AI smart control—AIROSD ensures stable, efficient heating. Installed in 120 + public buildings, it champions green heating in high-cold areas.

Heat pump floor-heating units extract ambient heat from air, water, or ground, compress it, and release warmth through subfloor exchangers. Achieving COPs of 3–4, they slash campus heating energy and CO₂ by over 30%. Equipped with smart scheduling, they operate reliably down to –25 °C and deliver uniform 35–45 °C warmth. Widely adopted in retrofits, they offer safe, efficient campus heating.

Heat pumps are attracting considerable attention due to their remarkable advantages. A heat pump is an efficient energy conversion device that transfers low-grade thermal energy from the environment into high-temperature heat, working similarly to refrigerators but in reverse for heating. It operates by compressing and expanding refrigerant in a cyclic process. This enables it to transfer a large amount of environmental heat with minimal electricity, providing both heating and cooling, thus being highly energy-efficient. Compared to traditional heating and cooling methods, heat pumps can generate 3 - 4 times more heat energy than the electricity they consume, reducing energy use by up to 50%. They are applicable in various scenarios: heating by extracting heat from the outdoors, cooling by reversing the operation, and heating domestic water with significant energy savings.

The celebration was not just a reflection of past accomplishments but also a glimpse into AIROSD’s future. The company’s relentless pursuit of innovation and excellence continues, and the event highlighted key advancements in their core technologies. AIROSD’s commitment to energy efficiency and sustainability was evident, particularly through its work in heat pump systems, which offer environmentally friendly solutions across multiple sectors. AIROSD’s heat pump technology has been optimized over the past year to provide more energy-efficient and eco-friendly solutions. The company’s heat pump systems have proven to be highly effective in reducing energy consumption, making them ideal for residential, commercial, and industrial applications. In the field of heat pump water heaters, AIROSD has set a new industry benchmark with products that are not only more energy-efficient but also have longer lifespans compared to traditional water heaters. The event also showcased the promising future of air-to-water heat pump systems, which harness thermal energy from the air to heat water, significantly reducing environmental impact. Furthermore, AIROSD’s heat pump technology is capable of both heating and cooling, offering efficient solutions for year-round comfort. To support the adoption of these green technologies, AIROSD has been actively involved in promoting Air Source Heat Pump System Grants, which make it easier for consumers and businesses to invest in energy-efficient systems through government subsidies. With certifications such as CE, Keymark, and A+++, AIROSD’s continued efforts to advance its technology and certifications help drive sustainability goals forward. The success of AIROSD Night not only celebrated the company’s achievements but also set the stage for the exciting innovations to come.
